Serial No. 224,937 Renewed August 5, 1939 38 Claims.

This invention relates to lasting machines, and is herein illustrated as applied to a bed-lasting machine constructed generally as disclosed in United States Letters Patent No. 1,284,870, granted on November 12, 1918 upon an application of Matthias Brock, but modified in certain respects as further disclosed in Letters Patent No. 1,495,169, granted on May 27, 1924 on an application of Joseph Fausse and Rene E. Duplessis. It is to be understood, however, that in various novel and useful aspects the invention is not lim-' ited to machines of the illustrated type. It is also to be understood that while the invention is herein illustrated and described with reference to operations performed on the toe end of a shoe, it is not thus limited in its applicability.

In one aspect, the invention has in view the provision in a lasting machine of means for conveniently and effectively applying heat to the portion of the shoe operated upon by the lasting means. It is contemplated that heat may thus be applied for any purpose for which it may be advantageous to use it, the present disclosure illustrating its use for the purpose of softening or activating thermoplastic cement previously applied to the insole for securing the margin of the upper in lasted position. In accordance also with the illustrative disclosure, the heat is applied not only to cement on the insole, but also to the margin of the upper which is to engage the cement, to afford better insurance that the cement will eifectively adhere to the upper. For the purposes in view the machine is provided with a heated member which engages the cement on the insole and also engages the margin of the upper as the latter is wiped inwardly over the insole by the lasting wipers characteristic of machines of the illustrated type. The invention provides novel means for supporting and controlling this member, the construction shown comprising a novel arrangement of swinging arms whereby the operator may conveniently move the member from an initial retracted position to a position overthe shoe and may also move it heightwise of the shoe into contact therewith. While the member may be heated in different ways within the scope of the invention, the machine herein shown is conveniently provided with a heater on which the member rests in itsretracted position and away from which it is carried when it is to be applied to the shoe. The above-mentioned arms comprise a manually operated arm arranged to extend generally lengthwise of the shoe and to be swung downwardly to press the heating member on the shoe, and another arm on which that arm is supported, this other arm being arranged to extend normally heightwise of the shoe but mounted to swing lengthwise of the shoe in a downward direction against'the resistance of a return spring in response :to a pull of the man? ually operated arm thereon to permit the heating member to be carried by the latter arm to a position over the shoe. To render the manually operated arm more effective as a lever in pressing the member on the shoe, a device is provided for locking the other arm againstreturn movement. The heating member, in the construction shown, is mounted on one end of a bartwhich extends lengthwise of the shoe and which is suspended by a link on the above-mentioned manually operated arm, the other end of this bar being connected by alink to still another arm mounted to swing lengthwise of the shoe in a downward direction as the member is carried to its position over the shoe. To permit the memher to be positioned more accurately in proper relation to the shoe and to be moved outwardly over the wipers while in contact with the margin of the upper, provision is afforded for moving it at the will of the operator lengthwise of the manually operated arm, this arm having mounted thereon a hand lever by bodily movement of which thearm itself is operated and by swinging move ment of which the above-mentioned bar may be moved lengthwise relatively to the arm.

In accordance with a further object of the invention the above-mentioned heating member, under control of the mechanism above described, may be and is herein illustrated as also used to press the margin of the upper against the wipers to render the wipers more effective to wipe the margin tightly over the insole and to assist in preventing the formation of objectionable wrinkles therein, the member thus performing the function of what is commonlytermed a retarder. It is to be understood, moreover, that the member may, if desired, be used for this purpose alone, in which case it may or may not be heated, the mechanism provided for controlling and operating it-being as useful and effective when the member performs this function as when it serves for heating purposes in the manner hereinbefore described.

The novel features of the invention, including various novel details of construction and combinations of parts, will now be more particularly described with reference to the accompanying drawings and thereafter pointed out in the claims.

In view of. the disclosure of features of the general organization of machines of the illustrated type-in the above-mentioned Letters Patent, the drawings show only as much of such a machine aslis necessary for an understanding of the invention, and such parts as are common to prior machines of this type will be only briefly hereinafter described. The shoe is supported bottom upward in position for the lasting operation on a post 2- provided with a pin l which enters the usual'spindle hole in the heel end of the last and on a-toe rest 5 (Fig. 4) mounted on another post 8.1 The shoe is clamped about its heel end by a heel band 50, and this end of the shoe may, if desired, be lasted in the usual manner, the margin of the upper being wiped inwardly over the insole by the use of heel wipers I2. For lasting the toe end of the shoe there are provided toe wipers M which embrace the upper about the toe and are operated by a hand lever IE to wipe the margin of, the upper inwardly over the insole, the wipers as usual receiving advancing a movement lengthwise of the shoe and closing movements laterally of the shoe. The toe wipers are supported by means which may be tipped in diiierent directions to adjust the wipers relatively to the shoe by the use of mechanisms which need not be herein described, these mechanisms and ,the wipers, together with the hand lever 16 and the means connecting it to the wipers, being all supported on a vertically movable slide 18 connected by a link 20 to a double-acting treadle 22. By means of this treadle, therefore, the wipers may be moved upwardly to wipe the upper height- .wise of the last before wiping its margin inwardly over the insole and may be thereafter lowered to press the margin of the upper down on the insole. The machine herein shown is also pro- ,vided with a toe band 24 controlled by the hand lever 16 for clamping the upper against the end and side faces of the last to assist in the lasting operation, such a toe band, however, being frequently omitted in machines of the illustrated type.

As thus far described, the machine herein shown is constructed as heretofore. For purposes of this invention a cover plate used heretofore over the toe wipers M is replaced by a different cover plate 26 formed integral with which is a bracket 28 arranged to extend lengthwise of the shoe. Pivotally mounted respectively on pins 30 and-32 (Fig. 3) on the bracket 28 are a pair of arms 34 and 38 spaced apart lengthwise of the shoe and arranged to extend normally heightwise of the shoe. Controlled in certain respects by these arms is a bar 38 extending generally lengthwise of the shoe, this bar having mounted on one end thereof, as more particularly hereinafter described, a plate 40 which is used to apply heat to cement on the toe end of the insole and also to the margin of the toe end of the upper and is further used to press the margin of the upper on the wipers in the toe-lasting operation. At its other end the bar 38 is connected by a link 42 to the arm 36'so that the bar may at times be moved lengthwise relatively to this arm. This link is held normally, however, in a relation to the arm 36 determined by engagement of a shoulder on the link with a corresponding shoulder 44 onthe arm. For this purpose a pin 46 is mounted in a socket in the arm with its outer end in contact with the link, the pin being urged outwardly by a spring 48 in the arm engaging a head on the inner end of the pin. In a location between its opposite ends the bar 38 is suspended by a link 50, bifurcated at its upper and lower ends, on a manually operated arm 52 which extends generally lengthwise of the shoe, this arm being bifurcated at one end and pivotally connected at that end by a pin 54 to the upper bifurcated end of the arm 33. Pivotally mounted between its opposite ends on a pin 56 carried by the arm 52 is a hand lever 58 provided with a handle 50, the lower end of this hand lever being connected by a link 62 to the same pin 64 which connects the bar 38 to the lower end of the link 5!]. By bodily movement of the hand lever 58, therefore, the arm 52 may be swung upwardly and downwardly about the pin 54 and may also be moved lengthwise, and by swinging movement of the hand lever about the pin 56 the bar 38 may be moved lengthwise relatively to the arm 52.

The arm 34 normally occupies a substantially vertical position, as shown in Figs. 1, 2 and 3, determined by engagement of a depending tail portion 66 thereof with a pin 68 on the bracket 28. The arm is held in this position by a spring connected to its tail portion and to a pin 12 on the cover plate 26. This serves to position the plate ll) over a heater M on which it rests under the influence of gravity, the heater consisting of a plate fastened to the cover plate 26 and having therein a recess in which is mounted an electrical heating unit for maintaining it in a heated condition. A shield 78 covered on the top with asbestos 85 guards against contact of the operators hand with the heater.

When the operator standing in front of the machine wishes to use the plate 40, which may be after he has raised the wipers by the treadle 22 to wipe the upper upwardly to the edge of the insole but before he has moved the hand lever I6 far enough to begin to wipe the margin of the upper inwardly over the insole, he takes hold of the handle 613 with his right hand and moves the arm 52 lengthwise to carry the plate from over the heater 14 to a position over the toe end of the insole which may have a coating of thermoplastic cement 82 (Fig. 5) in a hardened condition on its exposed face. At the beginning of this operation he may also swing the arm 52 upwardly enough to lift the plate from the heater. As the arm 52 is moved lengthwise its pull'on the arm 34 causes the latter to swing toward the shoe in a downward direction against .the resistance of the spring 10, and at the same time the arm 36 is swung similarly to the arm 34 by the pull of the bar 38 thereon. This bar, as above explained, may be moved lengthwise relatively to the arm 52 by use of the hand lever 58, and in order to insure proper clearance between the plate 40 and parts beneath it, if the parts are positioned initially as shown in Fig. 3, the operator swings the hand lever in a clockwise direction, with reference to Fig. 3, the resulting movement of the bar 38 relatively to the arm 52 being limited by engagement of a shoulder 84 on the link 50 with the lower face of the arm. It will be understood that in response to such movement of the bar 38 the arm 36 is swung relatively to the arm 34. It will be evident that by reason of the swinging of the pair of arms 34 and 36 as above described the plate 40 is carried downwardly toward the shoe as it is moved lengthwise of the shoe. The two arms are thus swung to substantially horizontal positions, in which positions they are substantially parallel to each other, the movement of the arm 34 being limited by engagement of a shoulder 86 (Fig. 3) on the bracket 26 with collars 88 (Fig. 2) mounted on the pin 54. A finger 90 fast on the bracket 28 also may serve by engagement with a shoulder 92 on the arm 36 to prevent this arm from swinging too far downwardly.

When the arms 34 and 36 arrive in their substantially horizontal positions the plate 40 is approximately in position for proper engagement with the toe end of the insole. The operator, however, exerts a further pull on the arm 52, as a result of which this arm is moved lengthwise relatively to the arm 34 by reason of the fact that the pin 54 connecting these arms together is mounted in slots 94 in the bifurcated upper end of the arm 34. A spring 96 connected to a clip 98 on the pin 54 and to a pin I on the arm 34 serves yieldingly to resist this movement. As a result of the movement of the arm 52 relatively to the arm 34 the pin 54 and the collars 88 thereon are carried into a recess I02 (Fig. 3) provided in a hook-shaped projection I04 on the bracket 28, as illustrated in Fig. 4., This serves to lock the arm 34 against return movement and causes the projection I04 to act as a fixed fulcrum for the arm 52 in the use of this arm as a lever to press the plate 40 down on thework. After the cement on the insole has been properly activated by the heat applied thereto by the plate 40 in the manner illustrated in Fig. 4, the operator begins to advance and close the wipers over the insole by means of the hand lever I6. First, however, by upward movement of the arm 52 he lifts the plate 40 far enough to permit the wipers to move inwardly under it. As he lifts the plate from the insole the operator swings the hand lever 58 in the direction to move the plate outwardly over the wipers, such movement of the plate and of the bar 38 on which it is mounted being permitted by the swinging of the link 42 against the resistance of the springpressed pin 46. The plate in this movement spreads the margin of the upper outwardly over the wipers, as illustrated in Fig. 6. Thereafter, while advancing and closing the wipers, the operator presses the plate 40 down on the margin of the upper, so that the plate acts as a retarder to render the wipers more efiective in wiping the upper tightly inward over the insole and to prevent any undue wrinkling of the mar gin. At the same time the margin of the upper is heated by the plate, so that the cement will more effectively adhere thereto. It will be understood that before the wipers complete their movement the margin of the upper is pulled entirely out from between them and the plate 40 and is wiped down throughout its width upon the cement-coated insole.

By reference particularly to Fig. 2 it will be seen that the mechanism for operating and controlling the plate 40' as above described is, for the edge contour corresponding substantially to the edge contour of the toe end of the insole, and its controlling mechanism is so constructed that when the plate is in contact with the insole it lies in substantially parallel relation to the plane of the wipers.

tipping movement of the wipers in adjusting them to the shoe, the relation of the plate 40 to the wipers is not affected by such adjustment. Provision is afforded, however, for tipping movement of the plate laterally of the shoe in response to pressure of the shoe against it, to afford further insurance that it will bear evenly on the cement all around the toe end of the insole. For this purpose a portion of the upper face of the plate is convexly curved laterally of the shoe, as shown at I06 in Fig. '7, and this curved face of the plate engages a complementally curved face onthe end of the arm 38. The plate is held on the arm by a pin I08 (Fig. 6) which is mounted for vertical movement in the end of the arm 38 and is provided at its lower end with a circular flange IIO having a convexly curved upper face arranged to be seated in a complementally formed recess IIZ (Fig. 8) in the plate. A spring I I4 serves by engagement with a collar I I6 fast on the pin I08 to urge the pin up wardly and thus to hold the flange I I0 in the recess H2. In order to permit the plate 40 to be readily detached from the arm 38 the plate is provided with a slot II8 extending from one edge thereof to the pin I08 and through which I the pin extends, the slot being wider than the pin so as to permit the plate to tip as above described. The operator may press the pin downwardly to release the plate and may then readily slide the plate out from under the end of the arm. In the construction shown the plate 40 has a serrated lower face to render it more quickly effective in softening the cement through the action of the heat applied thereto.

After the plate 40 has been used in the manner previously described it is returned to its initial position on the heater I4. It will be evident that when permitted by the operator the spring 96 serves to withdraw the pin 54 and the collars 88 thereon from the recess I02 in the hook-shaped projection I04, and that the spring i0 by its action on the arm 34 serves thereafter to return this arm and the parts connected therewith to their starting positions. The operator naturally lifts the plate 40 somewhat away from the shoe and the wipers by means of the handle 60 after the wiping operation, but he need not continue to control the parts by this handle until they are returned to their starting positions, since the hook-#shaped projection I04 is provided :with .an

Since this mechanism is supported by the cover plate 26 which partakes of any inclined face lit (Fig. 3) arranged toengage the portionof the link 62 adjacent to the pin 64 and thus to guide the bar 318 in its movement under the influence of the spring 10 so that the plate 46 will be returned properly to its position on top of the heater M.
